I know it was done before but after a lots of reading and trials, I just can’t make it work can someone help?
I have a Ublox F9P gps that I understand and know how to configure using U-center. I just want to send the plain GPS coordinate in te GPS port of the Pixhawk. In putty I confirm that the GPS send NMEA or any thing else require through it’s serial port. I then feed the Pixhawk GPS port with this signal.
I tried with NMEA and then with a bunch of other message including UBX. NO luck there.
I also tried to make everything in autodetect mode (from Qgroundcontrol → vehicule setup page). No luck either and Qgroundcontrol systematically freeze my GPS by playing with the setup. To a point that I fight with U-center rigth now to regain control of my GPS!
I think QGC is looking (waiting) for RTK fix. But I don’t want it nor use it for now. I have 3m accuracy and this is good enough for me right now.
I also don’t have a compass (or if there is one in my GPS, it is not configure). I read that heading of the compass and vehicule must match. That is not possible in my case.
I am using the following config:
QGC : 4.1.3
Rpi : 0.028
Pixhawk 2.4.8 (Pixhawk 1 I think).
edit: I know GPS don’t work underwater but in a pseudo-boat config it will.
